An apparatus for synchronously controlling the actual operation of a machine using one or more motors, such as servo motors, by simulating in program form a combination of selectable machine mechanisms, including drivers, connecting shafts, clutches, gears and cams. Each such machine mechanism is represented by a virtual mechanism, preferably as a software module that contains information uniquely identifying the module, operation information that defines the generation of position information and connection information that defines other modules to which connection is made. The software modules comprise drive modules for generating position information, transmission modules for simulating the transmission mechanisms and output modules for outputting motor commands.

In a method for operating controlled machines, a motion of at least one movable machine element of the machine is controlled using a motion profile specific to that motion, and this motion profile of the motion of the machine element is subdivided into a plurality of profile segments. Each of the profile segments is assigned at least one motion condition which influences this profile segment, and each motion condition includes at least one tripping event and at least one action event associated with this tripping event and tripped by the tripping event, and the action event influences the applicable profile segment.

Each time the number of cumulative rotations of a spindle rotating motor 11 reaches the number of cumulative rotations set in a position data table T, a CPU 22 reads out the mobile positions of a work piece and tool at thus reached number of cumulative rotations and the next number of cumulative rotations to reach from a position data storage section 25, and reads out a moving speed characteristic between the reached number of cumulative rotations and the next number of cumulative rotations to reach from a moving speed characteristic storage section 27 according to an auxiliary operation designation in the position data table T. Thereafter, assuming the reached number of cumulative rotations to be a start point and the next number of cumulative is rotations to reach to be an end point, the CPU 22 divides the part between the start and end points into predetermined timings, and defines the mobile positions of the workpiece and tool at each of the divided timings according to the read-out mobile positions of the workpiece and tool and moving speed characteristic.
摘要:
A reference variable having a linear relationship with the angular position of a master axis is set, and a correspondence between this reference variable and the displacement of a slave axis is stored in a data table. One execution stage is specified by setting a starting reference variable and an ending reference variable from this data table. A desired sequence is assigned to a plurality of execution stages thus specified. The reference variable corresponding to the angular position of the master axis is determined, slave axis displacement data corresponding to the reference variable is read out, and the slave axis is positioned in accordance with the position of the master axis on the basis of this displacement data.
